A rule of land use change in a mining city based on logistic regression model

摘要: 采矿作为促进我国经济发展的有效驱动力,往往伴随着剧烈的土地利用干扰。为研究矿业城市土地利用演变规律,本文利用土地利用矢量数据,借助ARCGIS软件、MAPGIS软件及SAS软件,分析了武安市土地利用结构变化和13年的土地利用变化趋势。在此基础上,运用logistic回归模型,得到该区土地利用变化规律随距离采矿区域距离变化趋势。结果表明:各类土地利用类型变化率随距离矿产资源分布区域的远近而呈现下降的趋势,但每种土地类型都会有一个特异性区段,呈现出不规则变化的状态;通过logistic回归模型分析,矿区对土地干扰强度最值并不在矿产资源分布区,在1996~2005年矿产资源分布区对土地利用变化的干扰半径小于2005~2009年间矿区的干扰半径。研究结果对于矿业城市土地利用规划具有指导作用。Abstract: It’s always going with land disturbance,when mining promotes the economic development of our country.ArcGis,MapGis and SAS software are applied to analyze the land use structure and changing trend of Wu’an city during 13 years.Logistic regression model is used to get land use variationwith different distances from the mining area.Theresult shows thatas the distance to mineral resources growing,the rate of land use change presents a downtrend,but each land type has a specific section,presenting the irregular change state.In addition,the mineral resources area is not the maximum value of the land disturbance,from 1996 to 2005,the disturbance radius of mining area to land use change is less than the disturbance radius from 2005 to 2009.The results of this study for mining city are of important guiding significance for land use planning.
